Abstract
This study evaluates the ability of embedded piezoelectric sensors (PZT patches) to detect damage in plain concrete beams subjected to impact loads using the Electromechanical Impedance (EMI) technique. A parametric study was conducted varying three parameters: impact height (2.5 m and 3 m), grade of concrete (M25 and M30), and position of the PZT sensors (center and 13rd distance from edges). The damage was quantified using statistical indices RMSD and MAPD, and the results were validated using finite element analysis. Experimental results showed a clear relationship between increasing damage and deviations in the admittance signature. The study concludes that PZT sensors effectively monitor early-stage damage and their performance varies with impact conditions and sensor placement.
